Abstract
Description
Die Erfindung betrifft ein Zellenpack mit mehreren mittels Vergussmasse zusammengehaltenen Einzelzellen die mit einem Pluspol und einem Minuspol versehen sind und im Bereich um den Pluspol Entgasungsöffnungen und gegebenenfalls innerhalb einen Stromunterbrecher (CID) aufweisen.The invention relates to a cell pack having a plurality of individual cells held together by potting compound which are provided with a positive pole and a negative pole and in the region around the positive pole have vent openings and optionally within a circuit breaker (CID).
Es ist ein Zellenpack bekannt, bei dem die Einzelzellen in Reihen und Spalten aneinander gereiht sind. Der Zusammenhalt des Zellenpacks wird dadurch erreicht, dass die zwischen den Einzelzellen dabei entstehenden Zwischenräume mit Vergussmase ausgegossen werden. Die Vergussmasse verbindet sich mit dem Außenmantel der Einzelzellen und hält diese in einem Zellenpack fest zusammen.A cell pack is known in which the individual cells are lined up in rows and columns. The cohesion of the cell pack is achieved by pouring the resulting between the individual cells gaps with potting. The potting compound connects to the outer jacket of the individual cells and holds them firmly together in a cell pack.
Die Einzelzellen können im Bereich um den Pluspol mit Entgasungsöffnungen versehen sein und im Innern einen Stromunterbrecher aufweisen, der bei einer Überlastung diese Einzelzelle aus dem Zellenblock abschaltet. Dieser bekannte Zellenpack hat den Nachteil, dass beim Vergießen die Entgasungsöffnungen verschlossen werden können, was zu einem unerwünschten Ausfall der vorgenannten Sicherheitselemente führt.The individual cells may be provided in the area around the positive pole with vent openings and inside have a circuit breaker, which in case of overload shuts off this single cell from the cell block. This known cell pack has the disadvantage that when pouring the vent openings can be closed, resulting in an undesirable failure of the aforementioned security elements.
Aus der
Diese Verhältnisse sind nicht mit den Bedingungen bei einem Batterie-Zellenpack von einzelnen Batterie-Zellen vergleichbar, da die Einzelzellen auch durch eine eingebrachte Verschlussmasse zu einer festen Einheit verbunden werden müssen.These conditions are not comparable to the conditions of a battery cell pack of individual battery cells, since the individual cells must also be connected by an introduced sealing compound to a fixed unit.
Dasselbe gilt auch für eine Batterie mit Elektrolyt, die in einem geschlossenen Gehäuse untergebracht ist, wie sie in der
Es ist Aufgabe der Erfindung einen Zellenpack der eingangs erwähnten Art zu schaffen, bei dem eindeutig sichergestellt ist, dass beim Einbringen der Vergussmasse in den Zellenpack keine Entgasungsöffnungen von Einzelzellen verschlossen und so die Funktionsweisen des Zellenpacks gestört werden kann.It is an object of the invention to provide a cell pack of the type mentioned in which is clearly ensured that when introducing the potting compound in the cell pack no vents closed by single cells and so the functioning of the cell pack can be disturbed.
Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.
Bei dieser Ausgestaltung des Zellenpacks sind die Einzelzellen im Bereich des Pluspols mit einem schmalen Schweißverbinder verbunden, vorzugsweise verschweißt. Dieser Schweißverbinder ist mit einem gleichen oder einem anderen Pol einer im Zellenpack daneben angeordneten Einzelzelle verbunden, vorzugsweise verschweißt. Die Stirnseiten über den Pluspolen mit den Entgasunsöffnungen sind mit Schaumstoffstopfen abgedeckt, die für aus den Entgasungsöffnungen der Einzelzellen ausströmendes Gas durchlässig sind. Diese Schaumstoffstopfen schützen jedoch die Entgasungsöffnungen und verhindern so einen Verschluss durch die Vergussmasse. Zwischen den Schweißverbindern und den Schaumstoffstopfen sind Aussparungen gebildet, durch die die Vergussmasse in die Zwischenräume zwischen den Einzelzellen des Zellenpacks eingebracht werden kann.In this embodiment of the cell pack, the individual cells are connected in the region of the positive pole with a narrow welding connector, preferably welded. This welding connector is connected to a same or a different pole of a single cell arranged in the cell pack next to it, preferably welded. The end faces over the plus poles with the Entgasunsöffnungen are covered with foam stoppers, which are permeable to gas flowing out of the vents of the individual cells gas. However, these foam plugs protect the vent openings and thus prevent closure by the potting compound. Recesses are formed between the weld connectors and the foam plugs, through which the potting compound can be introduced into the spaces between the individual cells of the cell pack.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar.Further advantageous embodiments of the invention are the dependent claims.
So kann in vorteilhafter Weise vorgesehen sein, dass die Schaumstoffstopfen aller Einzelzellen zu einer Schaumstoffmatte mit den Aussparungen einstückig zusammengefasst sind. Dabei kann die Außenkontur der Schaumstoffmatte an die Außenkontur des Zellenpacks angepasst sein. Dadurch wird die Herstellung des Zellenpacks mit wenig Zusatzteilen erleichtert und verbilligt.Thus, it can be provided in an advantageous manner that the foam plug of all the individual cells are combined to form a foam mat with the recesses in one piece. In this case, the outer contour of the foam mat can be adapted to the outer contour of the cell pack. As a result, the production of the cell pack is facilitated with little additional parts and cheaper.
Um die Abdichtung des Pluspols noch zu verbessern, sieht eine weitere Ausgestaltung vor, dass zwischen dem .Pluspol und den Schweißverbindern Dichtungsringe angeordnet sind, die den Bereich des Pluspols mit den Entgasungsöffnungen gegenüber der Außenkontur der Einzelzelle abdichten.In order to improve the sealing of the positive pole even further, provides a further embodiment that between the .Pluspol and the weld connectors are arranged sealing rings which seal the region of the positive pole with the vent opposite the outer contour of the single cell.
Damit wird sichergestellt, dass selbst dünnflüssige Vergussmasse nicht über den Rand der Einzelzelle in den Bereich des Pluspols eindringen und die Entgasungsöffnungen verschließen kann.This ensures that even low-viscosity potting compound can not penetrate beyond the edge of the single cell in the region of the positive pole and close the vent openings.
Die Verbindung der Einzelzellen im Zellenpack in Reihen- und Parallelhaltung wird dadurch erreicht, dass der Schweißverbinder gleiche Pole oder ungleiche Pole benachbarter Einzelzellen miteinander verbindet.The connection of the individual cells in the cell pack in series and parallel position is achieved in that the welding connector connects the same poles or unequal poles of adjacent individual cells.
Die Herstellung des Zellenpacks wird dadurch noch vereinfacht, dass die Schaumstoffmatte auf der dem Zellenpack zugekehrten Seite mit einer selbstklebenden Schicht versehen ist. Die Verbindung der Schaumstoffmatte mit dem Zellenpack ist dann ein einfacher Klebvorgang.The production of the cell pack is further simplified in that the foam mat is provided on the side facing the cell pack with a self-adhesive layer. The compound of the foam mat with the cell pack is then a simple gluing process.
